Ink Blot welcomes you to Lance's Web Site!

I've decided to resurrect my web site on a limited basis; mainly to discuss FAT32X, but also to test a new site build process. LC

DISKZERO

Disk Eraser

Download

DISKZERO.ZIP or DISKZERO.EXE

Description

This program erases a disk by writing 00h to all sectors of the disk.

Help

C:>diskzero -?

DISKZERO (01.00, 05/03/98) - Disk Zero
usage: DISKZERO (DRIVE) -Z

DISKZERO (01.00, 05/03/98)

DISKZERO writes 0x00 to all bytes in all sectors on a disk drive.
This effectively removes all the partitions, data, etc on a drive.
If you don't understand what was just said, let me reiterate:
  THIS PROGRAM WIPES OUT YOUR DRIVE BIG TIME!
You will, of course, be given the chance to abort the process before
it starts.  After that, its your loss if you make a mistake.
Suggestion:
  Don't leave this program on your hard drive.
  Put this program on a bootable floppy and put it in a safe place.

(DRIVE) specifies the physical disk drive.

-Z is a required parameter.

Sample Execution


Functionality

Parse parameters. Determine disk geometry based on Int13 extensions. For each cylinder+head, write out a zeroed data track.

Notes

DISKZERO destroys all data on the disk. Use with caution.

DISKZERO can take quite a while to run.

DISKZERO cannot erase parts of the disk it cannot see, i.e. only about 8GB (1023x255x63 sectors) of a 10GB drive in a computer without Int13 extensions would be erased.
